f IMPROVEMENT IN MUcILsesnNo MARKING-Baumes.,

Be it known that I, WILLLAM R. Asrn-znsox, of the city, county, and State of New York, `have invented certain new and useful devices in the construction of Mucilage and hlarking-Brhshes5 and I hereby declare that the following is a full and sufficient description thereof, reference being had to the aceonnpanyinr drawings and references which make part ofthe saine.

The invention consists in the mode of making the fastening of the uiucilage brush, that is, the bristles,`and

holding them, but particularly thc holding of thc bristles in place on the outside of the tube around Whiclrtheyl are arranged. The necessity of the case is that the liquor which feeds the brush must come orlovv through the handle. The bristles, therefore, must be arrangedion the outside in order to secure theurand bind them firmly and keep them from the direct contact' with the liquid which flowsalong the inside of the tube, and would have the effect, it' Ain directeontact, to soften the cement used to fasten the bristles in place. The bristles are fast I cned to the periphery of the pipe or tube, and by means of a cement, which isy regarded insoluble in water,

although most of this class ot' cenents are vso softened by the presence of water as to require soule extra aid t0 sustain them in pla-ce. The' ordinary mode `of sustaining the bristles in place is to ivind twine `orsmall vire around the bristles. This device, however, does not prevent-the contact of the liquid with the 'outer surface, and so, by degrees, meisten and soften the cement. My device consists in screwing down uponlthe surfacel of the bristles a tube slightly conical on the inside, and thus l'lls up thclspace between the two and prevents th ingress of any iiuid from without, and, pressed equally upon every part of the lbristled surface, makes a 'fine iinsh and durable article. In the accompanying drawingsl Figure 1 represents an elevation of the screw cap to'be fitted on the -neek of the mucilage bottle.

Figure 2 is a sectional elevation in the lineJc x oi iig. 1.

Figure 3 is a vicw of the filtering metallic plate a a, seen on under side.

Figure 4: is an edge view of plate a a, the under surface being convex.

Figure 5 is an edge view4 of the rubber gasket c.

Figure 6 is a top view of' the rubber gasket c.

Figure 7 is an elevation of the screwfastening band d for the bristles.

Figure 8 is a top view of the fastening-band d.

Figure 9Vis an elevation of the metallic covering cap e of the brush.

Figure 10 is a top View ot' the same.

`Figure 11 is an elevation of the cap and brush in position for receiving the covering ca er Figure 12 is a top view of the cap and brush Without the covering cap e.

To enable others skilled in the art to makean'd use my invention, I will describe it somewhat in detail.

The principal parts are made from what is called Britannia vvare, or lead, or other-desirable metals. l The screwcap c may be cast, when the article is large and required to be heavy, but it may be made of spun metal,

and the screw is also spun on the sides of the cap. The' bristle tube around which the bristles are arranged, is also spun u-p from the cast inet-al, and the bristles are laid around it in lines parallel with the axis,`ready .t0

be cemented to the outside of the tube preparatory to adapting ythe 'fastening-band which grasps firmly the i bristles and holds them in place. The tube z' is covered with shellac or otl'relfsuitable cement, and, Whilein the plastic sta-tc, the bristles are adapted thereto and fastened temporarily tillfthe fastening-band or shield is ready to be screwed into its place, covering and protecting thc bristles from wet. The brush and fasteningband, havinfnr been completed, the gasket c is lai(A 1 on the mout-l1 of bott-le g g, and the ilteringfplate or disk ais placed on it with the convex ysurface downward, or both placed inside of cap-c in thesa'nie position,'and the screw cap e is firiniy screwed into its place on the mucilage bottle, which bottle, having been charged with nlucilage or its equivalent, which is oneI ounce et' gum arabic and three ounces of water, or any other like proportion, after standing three or four hours the bottle is readyjfor use. i y

'lo use the bottle and brush as a lnucilage or marking-brush, remove the covering cap ctaud invert the bottle, holdinfaY it firmly in the right hand, either paste or write as you have occasion to do. "When the Work is completed, replace the bottle in its original position and place cap cover c over the brush, which prevents expos sure of brush to the air, and thc evaporation of the mucilage passing oil' through the brush, the hardening of Y the same is prevented, and always remains moist and ready for use.

Having fully described my fountain-brush and the metlio'd of using it., what I claim as my invention, and desire to secure bylietters P11-tent, is

The combination of the shield tubo d with the cemented suifuce f the brush tube 1f for excluding moisture,

and folirning a durable shield-fastening substantially in the manner set ioth.

' I also claim, in combinnton with the reservoir, the {Utoring-plate rl, fr', substmiiully as sct'forth.

WM. R. ANDERSON.
